    The magnetic mine only worked because ships' hulls concentrate the earth's magnetic field (N-pole down). Applying a sufficient reverse field for a short period would leave the hull magnetized in the 'wrong' direction and thus counteract this increased field, rendering the ship undetectable (for a while).

  • Lightning Myths - Small metal objects attract lightning

    TRUTH: For all intents and purposes, nothing 'attracts' lightning. Lightning occurs on too large of a scale to be influenced by small objects on the ground, including metal objects. The location of the thunderstorm overhead alone determines where lightning will hit the ground. A lightning bolt that is several miles long, generated by a cloud that is more than 6 to 10 miles high, is not going
